I rather like the Stargazer design, but I agree it's a shame we never saw any other Refits during the course of TNG (at least any intact
ones that weren't destroyed by the Borg). Especially considering how many OTHER reused models we saw from the movies. Or how many sister ships the Enterprise had in TOS that could have also been refit.
I'm sure the studio wanted to reserve the Refit as something special for the movies at the time, but still. Would have been cool to see.
